Hi group,
I've become interested in Python a while ago and just converted a simple
perl script to python. The script is very simple, it generates a list of
found virusses from some maillog files for further processing.
I've found that there's a huge difference in execution time for the scripts,
in favor of perl and I can't pinpoint what's going wrong;
perl runs:
0.07 real 0.05 user 0.01 sys
0.07 real 0.05 user ...

I'm currently reading 1-n number of binary files, each with 3 different
arrays of floats containing about 10,000 values a piece for a total of
about 30,000 values per file.
I'm looking for a way to load them all into memory. I've tried using
vector pushback with reserving, but it was horribly slow. The current
method I am using is upon opening the file and reading the number of
values, resizing the vectors (I have 3, one for each data...

I have a simple 192-line Python script that begins with the line:
dummy0 = 47
The script runs in less than 2.5 seconds. The variable dummy0 is never
referenced again, directly or indirectly, by the rest of the script.
Here's the surprise: if I remove or comment out this first line, the
script takes more than 15 seconds to run. So it appears that adding a
redundant line produces a spectacular six-fold increase in speed!

Hi,
While on the topic of "need for in-place upgrades", I got to think-
ing how the pg_restore could be speeded up.
Am I wrong in saying that in the current pg_restore, all of the
indexes are created in serial?
How about this new, multi-threaded way of doing the pg_restore:
0. On the command line, you specify how many threads you want.

I am trying to access the data with in a wav file. I am testing with very
small files in order to keep the code simple to start with.
Basically, im writing the entire wav file to a byte using a fileStream.
The problem is that when reading back the data word by word and printing the
results on a general form, once the data chunk header has been read, i.e,
"data" and "chunk size", all the rest of the bytes in the array have the
value...

First thx for your quick answer :)
iostat dont return bad load average. I never grow up to 1Mb/s and the
IDE drive can go faster.
I really can't change the server, its a locative server which i own
(only me on the server, no cooperative, but i dont have physically
access to it). So the configuration is ... not the best :). And at this
time, i dont have money for server-hosting.

Yello,
Quick Q:
What is the fastest way of getting data from a file?
Does the though put of the file increase if I collect
a great big chunk of it? Eg say 6meg? or does that
even help?
Does a bufferedstream work better if I am just going
to open a file and read it?

I want to join two mono wave file to a stereo wave file by only using
the default python module.
Here is my program, but it is much slower than the C version, so how
can I increase the speed?
I think the problem is at line #1, #2, #3.
import wave
import array
lfile = wave.open(lfilename)
rfile = wave.open(rfilename)

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies.

These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention.
